2015 Toyota Prius Persona special edition arrives in September

Is the Prius going into "Pimp My Ride" territory? A new official special edition model won't be lowered or have three-wheel motion or anything like that (though that'd be cool), but the world's best-selling hybrid is putting on a few stylish bells and whistles this September. Toyota has announced something called the 2015 Prius Persona Series Special Edition. Included on the special variant will be 17-inch alloy wheels, a metallic exterior finish, heated power mirrors and chrome shift knob rings and door grips. Inside, you've got special badging and black SofTex fabric stitched with gray. The new Prius Persona will come in two colors: "Blizzard Pearl" and "Absolutely Red." The special edition has base price of $26,985, and the "Blizzard Pearl" option knocks it closer to the $27,400 mark and there's also the $895 (give or take) delivery fee. Demand for the Prius in the US has plateaued recently as other automakers have broadened their selection of advanced-powertrain vehicles. Through the first half of the year, combined sales of the four Prius variants were down 11 percent from 2013 numbers to about 107,000 units, including about 63,000 of the standard sedans and almost 20,300 of the Prius C compact hybrids. Perhaps there are enough personas out there that sales will get a boost from this special edition. Take a look at Toyota's press release on the 2015 Prius Persona below. SPECIAL EDITION PRIUS TAKES ON A NEW PERSONA FOR 2015 TORRANCE, Calif. (July 30, 2014) – The best-selling hybrid in America is taking style to a new level. The 2015 Prius Persona Series Special Edition is tailored with elegant exterior and interior touches that make it unique. The special edition model will begin arriving in dealerships in September. The Prius Persona Series Special Edition model adds exterior changes and equipment to a Prius Three to create a distinct visual package. Persona Series includes 17-inch alloy wheels with a premium dark metallic finish. The special edition also comes equipped with premium heated power mirrors with turn signal indicators. The Persona model will be available in two exterior colors, Blizzard Pearl, and for the first time ever on this model, Absolutely Red. A "Persona Series" exterior badge on the rear of the vehicle also helps differentiate the model. The Persona's interior is trimmed in black SofTex® with gray stitching.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Recharge Wrap-up: 'Racing Extinction' Tesla, Wards praises 3 hybrids

The makers of Racing Extinction used a tricked out Tesla Model S for their movie. The artists and activists used the electric car as a platform to project images from nature in various cities to raise awareness about imperiled wildlife. In addition to a the high-powered projector, the Model S features a electroluminescent paint job that emits light to mimic creatures found in the wild, such as bioluminescent sea life. It also has a thermal imaging camera in the front of the car with a filter to view CO2 emissions. Check it out in the video above, and read more at Ecomento. WardsAuto has named the 2016 Hyundai Sonata Plug-In Hybrid's powertrain to its list of 10 Best Engines. As the first plug-in hybrid to make the list, WardsAuto World Editor-in-Chief Drew Winter praises Hyundai engineers for their "impeccable job blending fuel efficiency with refinement and daily usability." Wards notes the car's smooth transitions between electric and hybrid modes, and a well-connected six-speed automatic transmission. Other electrified vehicles to make the list are the 2016 Chevrolet Volt and 2016 Toyota Prius. Read more from Hyundai, at Green Car Reports. FEV's plug-in hybrid battery pack has gone into vehicle series production. The 10-kWh battery pack, developed by the German development services provider, offers an all-electric range of about 30 miles. FEV says its battery management algorithms are just as important as choosing the right battery hardware. "The core system for the battery development is our own mature battery management system (BMS), now in its third generation, that together with optimized algorithms allows a very reliable and stable control of the battery," says FEV's Dr. Michael Stapelbroek. Read more at Green Car Congress, or in the press release from FEV below. Hybrid Vehicle Goes Into Series Production FEV development competence consists of batteries, controls, as well as complete drive systems FEV has demonstrated competence in the development of alternative drive concepts for almost twenty years. Most recently, yet another plug-in hybrid vehicle has gone into series production with technology provided by the Aachen-based developer. In addition to using an innovative transmission concept which is based on a FEV patent, FEV also developed the battery technology of the plug-in hybrid vehicle to series production readiness.
